Car has come alive. I was weary on if I should get the extreme or muffled version but opted for extreme. Cold starts are loud but once the car idles, it becomes very reasonable. Basically in the sweet spot and balance between loud but no abrasive. Virtual no cabin drone (not abalrasive, can hold a conversation and can hear music even with the terrible subaru sound system lol). Brings out the rumble in an un-obnoxious way while idling but once you get on it, the car reacts and becomes a demon. 10/10 recommended. It has that “adult” loudness and factor to it. Doesn’t sound like a fart can and I have been getting a TON of compliments on the sound from non-car friends which confirmed that this exhaust is legit. Fitment was scary good, especially with v-bands. If you’re on the fence, get the extreme.
